I found out that if I remove

<p>&nbsp;</p>

and

<noscript>...</noscript>

then the test succeeds

however the nesting is still wrong. (2nd audio tag gets rendered into the first one)

[rburgst]

note that I also tried sanitizing the html beforehand (as suggested here remarkablemark/html-react-parser#124), the result is still the same.

I guess the problem is that we cannot specify {xmlMode: true} to htmlparser2

I fixed the issue with parsing HTML entities in the test runner (see explanation in issue #25 or 41679f9).

I also discovered that the jsdom version we're using is not properly parsing <noscript> children so I skipped those tests (see 40ade7e).
